fix(pedm): CryptCATAdminCalcHashFromFileHandle2 does not return error with NULL buffer

[thenextman]

The CryptCATAdminCalcHashFromFileHandle2 documentation says:

Return value

[...]

ERROR_INSUFFICIENT_BUFFER | The buffer pointed to by the pbHash parameter was not NULL but was not large enough to be written. The correct size of the required buffer is contained in the value pointed to by the pcbHash parameter.

Ergo, the function will not return an error when passing a NULL value for pbHash, it will succeed. This is confusing because other similar Win32 APIs do not work the same way.
